摘要
针对移动支付的多应用安全需求,首先在RFID智能卡和对称密钥技术的基础上,提出了多层密钥体系和密钥管理系统;然后研究了系统中密钥的管理流程;最后介绍了系统所采用的密钥安全技术。所提出的多层密钥体系和密钥管理系统,引入了与第三方合作类业务的密钥,同时支持PSAM卡二次发卡,比目前常用的密钥管理系统具有更好的可管理性和方便扩展性。
In this paper,for the multi-application security requirements of mobile payment,the multi-level key system and the multi-level key management system based on the RFID smart card and the symmetric key technology are proposed.And then,it is devoted to the processes of the key.Finally,the key security technologies used in the key management system are described.The proposed multi-level key system and multi-level key management system,which support the key of the business which cooperate with the other companies,and issuing the PSAM card twice,are more flexible and stronger than the common key management system.
